Subsea Integrity Laser-Inspection Technology Provides Vital Insight for Marine Benthic Researchers
Marine science researchers have successfully integrated Savante's underwater laser profiler technology aboard a low-cots towed benthic sledge equipped with solid-state LED lighting and video cameras. Deployed from a fishing vessel on a towing harness; sub-millimeter accurate micro-topographic seabed surveys have been recorded over a variety of cobble and Sabellaria worm reefs.
Combining ground-truth video footage with data provided by Savante's real-time, synchronised underwater laser profiler; researchers precisely determined the height of discrete outcrops of worm reef and cobbles on the seabed. This enabled a more accurate understanding of the benthic environment and the identification of important reef features. Laser scan data was recorded in shallow waters throughout the day in the presence of significant ambient lighting; marking a unique breakthrough in the development and application of the technology.
